Abstract

In this paper, the major reasons for using of partial-admission technique in supersonic turbines are described. Then, a summary of the design process of supersonic turbine test rig is presented. This test rig is used to produce the turbine characteristic curves. Gasdynamic similarity calculations are described and the standards for how to install and use the measurement systems in the turbine test rig have been introduced. The turbine characteristic curves obtained in this work have been compared with the results of the turbine performance prediction code and the other works. Considering the validated performance code, the results of the test rig are acceptable. Also, the model turbine efficiency at partial-admission condition is 20 units less than full-admission condition.cceptable.
